It's cheap in terms of money but costs a LOT of time.

In a previous job I managed a mail server and I probably spent a third of
my working hours just dealing with tuning spam filters and trying to keep
the system usable and secure under the deluge of spam and abuse.

I also used to run my own home email server, but I found it ate way too
much of my free time; also, IMAP isn't really a good solution when you have
three or four different devices, and none of the open-source web UIs worked
well for me.

Even the central IT department where I work has come to the same conclusion
-- they no longer run their own email servers, but contract out to Google
and Microsoft for it.

Re: [OpenIndiana-discuss] SSD as a dedicated swap device

Hmm.  I could see that working for small systems, but I have some machines
where that would require dedicating a terabyte of disk to swap.  That
doesn't seem reasonable, especially when the root partition is on an SSD
that may itself not be much bigger than core RAM.

It also never really made sense to me why you'd increase swap when you add
more RAM.  It seems like a system with more RAM would need *less* swap.

The recommendation for a while was 2 x core, but I think that stemmed
partly from Linux using a virtual memory implementation at the time that
couldn't swap properly if swap was smaller than that.  These rules of thumb
tend to start for logical reasons but then carry on as cargo cults long
after -- sort of like how I still see people setting
"rsize=32768,wsize=32768" on NFS mounts to "improve performance." :)

That would certainly be interesting to have such stack in oi-userland if

We use a combination of sendmail, procmail, MailScanner, and dovecot at my
work, and it works a charm on multiple devices (significantly better IMAP
with dovecot than any other we have tried)

The greatest issue with our current setup is not the clients but sending
mail to our customers and suppliers, especially since August last year.
Microsoft updated something and we have severe trouble sending _some_
messages to any server running exchange, even with SPF and DKIM running
successfully.  Mostly this is down to badly configured exchange servers,
but the blame always comes back to us.

When our company recently split, I advised the part without me to move to
Google mail, and they haven't looked back.

Just my 2cents

As with many things, I've found over the years that it depends on the
audience.  A lot of people in workplace environments don't have time to
carefully do a scavenger hunt through a long post to find the buried
inlined comments, and will ignore anything not at the top.  On the other
hand, for responding to a detailed point-by-point discussion inlining makes
sense, and it does make people slightly more likely to actually trim their
quoted text.

I think generally it's best to follow whatever pattern already exists in a
thread.  It's a mix of the two posting styles that really gets confusing.
Other than that I don't feel strongly enough about it to get ideological
about it.  I don't think there's One True Way to use email. ;)

I sometimes wonder how people using screen readers would feel.  Does the
extra context of inlining help, or is it just tiresome and confusing to
listen to multiple paragraphs of old stuff before getting to hear the new?

[OpenIndiana-discuss] MPI libraries and OpenBLAS

2015-12-15 Thread Aurélien Larcher 
Hello,
as part of a winter cleaning session on my workstation some updates to
hipster-2015 for scientific computing lovers:

- mpich [1] to 3.2 with 32/64bit, C+FORTRAN, support for ch3:sock only
- openmpi [2] to 1.10.1 with 32/64bit, C+FORTRAN
- openblas [3] to 0.2.15, multithreaded with dynamic arch support but
PRESCOTT as minimum, 32bit only kernels are disabled.

MPI libraries are managed by environment-modules [4] as it should... or at
least as customary on supercomputers and other cluster animals...
Therefore you need to install the modulefiles and module load
mpich/gcc/(32|64) or  openmpi/gcc/(32|64) beforehand.

My experience was that different IMAP clients using the same mailbox would
"fight" each other over which emails were deleted, which were new, which
were in different folders, etc. The result was a mess.  Email showed up
twice, email went missing, email ended up in unexpected places, and junk
status messages got inserted (I'm looking at you, Pine.)  I also use email
sorting rules extensively to manage mail from mailing lists, and having to
re-create the same rules on each and every client (some of which were not
really capable of it) was very tiresome.

I used spamassassin back in the day, plus some ad hoc rules in Exim.

Does IMAP with a modern IMAP server like Dovecot work better with 
multiple devices?


What you describe is definitely the case for the original University 
of Washington IMAP server (which I am still using).  Actually, this 
server works ok with Pine/Alpine as a client (only one connection 
allowed at once) but there was an all-out war between Thunderbird and 
Apple iPad email.

Google and Microsoft data-mine the emails for their own benefit.  I am 
a independent sort of person so I prefer to mine my own emails.

As much as I would love to do this, currently Spamdyke relies on qmail 
to deliver mail. Sam is working on changing this in the next version.  
It also doesn't support IPV6, which is also being worked on.  Once these 
are in place I'll be glad to set it up for oi-userland.
